Michele Bachmann on Wednesday said she has "decided to stand aside" and is ending her bid for the Republican presidential nomination after her last-place finish in the Iowa caucuses.

The conservative Minnesota congresswoman's decision, widely expected following her Iowa showing, leaves her supporters up for grabs by the other candidates in the race, particularly former Pennsylvania Sen. Rick Santorum, former House speaker Newt Gingrich and Texas Gov. Rick Perry.

Republican Michele Bachmann announced Wednesday she would end her presidential campaign.

"I have decided to stand aside," Mrs. Bachmann said at a news conference hours after the caucus results were announced. "I will not be continuing in this race for the presidency."
